GLASS-GUTT1NG IMPLEMENT.

Application filed January 6, 1925.

This invention relates to a glass cutting implement.

It is primarily aimed to provide a means whereby the point or glass cutter in an implement of this character may be readily removed for sharpening, repair or replacement.

Another object is to provide a novel and eflicient construction to carry out the end aforesaid and one which particularly includes a detachable bracket having an angularly disposed end seated in the end of the implement and in coaction therewith, mounting the cutter, the bracket having a side portion adjustably connected to the implement, and the bracket being capable of manufacture from a single strand of wire. Additional objects and advantages will become apparent from a description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings Figure 1 is a side elevation of an implement embodying the invention.

Figure 2 is a fragmentary plan view on an enlarged scale.

Figure 3 is an end view on an enlarged lca-le.

Figure 4.- is av detail perspective view of the bracket, and

Figure 5 is a detail elevation of the forward end of the implement.

Like reference characters designate like or similar parts in the different views.

Referring specifically to the drawings, an ordinary and conventional glass cutter or glaziers implement is shown at 10 which has a handle 11 and a head 12 integral therewith and provided with a plurality of slots 13 for engagement with scored or cut glass in order to assist in the breaking thereof.

In accordance with my invention, a bracket 14. is provided preferably, though not necessarily, being made from a single strand of metallic wire as shown. This bracket has a side or attaching portion 15 which is returned at its distal end at 16 to provide a loop having a slot 17 through which a set screw 18 passes. Set screw 18 is Serial No. 872.

threaded into the head 12 and serves to removably clamp the bracket 14; in place.

The front end of bracket 14 is angularly disposed to form a journal 19 for a glass cutting disk or the equivalent 20. The head 12 is slotted at its forward end in order to provide clearance for the location and accommodation of the cutter 20 against movement laterally or longitudinally of the journal 19. The forward end of the head is also notched at 21 so as to receive and rigidly hold the journal 19.

When it is desired to remove, inspect, repair or replace the cutter or equivalent 20, the setscrew 18 is loosened, whereupon bracket may be moved forwardly so as to space the journal 19 from the head and thus permit removal and replacementof the cutter, or if desired, this result may be accomplished by completely detaching the bracket. When the cutter is on the bracket and properly replaced with the latter on head 12, the parts are securely fastened in place by the tightening of screw 18.

I claim:

1. An implement of the class described having a head provided with a bifurcation, a cutter extending into the bifurcation and a bracket on the head journaling said outter and slidableto move said cutter there with and out of the bifurcation.

2. An instrument of the class described having a head provided with a bifurcation,

a cutter extending into the bifurcation and a bracket on the head journaling said cutter,

said head being notched adjacent the bifurcation and the bracket extending into said notches for the purpose specified being slidable to move out of the bifurcation and notches.

3. An implement of the class described having a slot adjacent one end thereof and notches at said end extending at right angle to the slot, a bracket secured to the head having a journal extending into said notches, and a cutter on said journal extending into said slot, said bracket being slidable to move out of the bifurcation and notches.

4. An implement of the class described having a slot adjacent one end thereof and bracket notches at said end at a right angle to the slot, a. bracket made in a single strand having an attaching loop, means coacting with said loop to connect it to the implement, said having an angularly disposed journal at one end thereof occupying said notches and. a cutter on said journal extending into said slot, the construction onabling the bracket to be moved longitudinally of the implement to disengage the bi- 10 fnrcation and notches.

In testimony whereof I my signature.
